The lake-filled Akademia Nauk caldera, seen here from the north with Kaymsky in the foreground, is one of three volcanoes constructed within a large mid-Pleistocene caldera. Two nested calderas, 4 x 5 km Odnoboky and 3 x 5 km Akademia Nauk formed during the late-Pleistocene. The first historical eruption from Akademia Nauk took take place on 2 January 1996, when a brief, day-long explosive eruption occurred from vents beneath the NNW part of the caldera lake.
